UNITED STATES PATENT OFFICE PBIMING SOLUTION FOR WALL PAPER AND LIKE PASTES George Littig, Sacramento, Calif.

No Drawing. Application September 28, 1934, Serial No. 745,938

2 Claims.

The present invention relates to a new improved composition of matter and has especial reference to a solution for admixing with wall paper or like pastes to produce a priming compound of a more potent character than the usual pastes utilized in hanging wall paper.

The usual practice in hanging wall paper is to first size the surface of the walls before applying the wall paper thereto, but in the use of my improved compound it is unnecessary to do this sizing work beforehand by the use of acids, vinegar, or any other form of treatment now commonly used in the trade.

It, of course, is to be understood that the walls must be clean before any wall paper paste should be applied to the same to cause the proper adhesion of the paper or cloth to these surfaces whether they be painted, varnished, or polished surfaces or whether they be tin, metal or glass substances or surfaces.

The primary object of my invention is to produce a simple, cheap and eflicient compound that may be added to wall paper paste in the proper proportion to prFdEEY'idteiit" compound or paste that enables the paper hanger to readily apply wall paper to any surface such as sand finished plaster, kalsomined walls, painted, polished or varnished surfaces, or that may be used as an adhesive compound in connection with wood, plaster or metal surfaces, or on tins, cans, or bottles without sizing or treating these surfaces in any way.

A further object of my invention is to produce a priming compound that enables the paper hanger to eliminate the sizing operation entirely which saves considerable time and labor and at the same time produces a better job at less cost than the usual job of this character and one that will not only be more permanent but that will be much improved in appearance as well.

A still further object of my invention is to produce a priming compound of the character specified that employs simple and few ingredients and that will be very cheap to compound for the market.

The usual paste utilized by all paper hangers for commercial paper hanging consists of a paste compounded in the proportions of substantially two (2) pounds of paste to one (1) gallon of water and to this paste is admixed four (4) ounces of the riming compound which compound consists 0? the following chemical solution in the proportions or substantially in the proportions set forth as follows: V

Fifty (50) parts solution of silicate of soda, or water glass, which is poured m' to a glass Ev owl or bot le an to this silicate of soda is added forty-four (44) parts of water at a temperature ranging from 40 to '70 degrees Fahrenheit after which this solution is then well mixed.

To the silicate of soda and water solution as above set forth is then added six (6) parts of a twelve-and-one-half percent (l2 copger sulphate solution after which the solution is we stirred or agi a d to cause the thorough admixing of the compound.

The formula for the priming compound is as fo ows:-

50 parts solution sili ate of soda (water glass).

44 parts of water ranging from 40 to '70 degrees Fahrenheit; a

6 parts of a 12 co r sul hate solution.

t will thus be observed that I have prauced a compound which not only renders adhesive paste of the character set forth much more efficient but also produces a period and also artisan much simpler in that the use of the solution entirely eliminates the sizing operation which is necessary with the paste now used for the purpose, furthermore, the paper will set better on the wall and will not likely wrinkle or become loosened as is the case with the ordinary wall paper paste as set forth hereinbefore.

The compound may be put up for the market in small vials of an ounce or larger size and it is to be understood that the method of compounding may be varied somewhat in proportion as to the ingredients used and that such slight variations will come within the scope of my invention as set forth in the following claims:-

I claim:-

' l. A priming compound for the mixing with wall paper and like pastes consisting of an admixture of ingredients in the following proportion: 50 parts solution silicate of soda, 44 parts of water, and 6 parts of a 12 copper sulphate solution.

2. The method of producing a priming compound for admixing with wall paper and like pastes consisting of placing 50 parts silicate of soda (water glass), in a glass container, adding 44 parts of water thereto at from 40 to 70 degrees Fahrenheit and then mixing well, then adding to this admixture 6 parts of a l2 copper sulphate solution and finally agitating the entire admixture to cause the thorough mixing of all ingredients of,the solution.
